Not saying that Aleix lied but am well aware that some people hear what they want and from that will determine a story as they already have in their minds what occurred on track.
IMO only but there is no doubt that Aleix believes that he heard Webb in the way he has described, now whether Webb said those words or was not clear and thus Aleix has interpreted his way, that could be another story.
Personally, just as I do not think Aleix lied I also do not think that Webb has necessarily lied as what I do feel is that both are making statements based on the point that puts them in the best light from their own points.
He did not tell Marquez that he had done nothing wrong, he said that no rules were broken and whilst that may exonerate Marquez of blame in the incident, it does not mean that in the eyes of RD Marquez was totally without blame or reasonable cause (he stated that RD had suspicions)
My take may be disturbing but my take is based on years of experience where people hear and repeat that which they wish, in a manner that is beneficial to themselves and where two people are speaking, often the truth lay somewhere in the middle. As the saying goes 'what you hear and what I hear is often different despite the words being the same'.
To me, the sheer fact that Aleix was NOT called to Race Direction means that any discussion was unofficial and no matter what Webb says, it is not binding as it was unofficial. If Webb was of the belief that AE did impede at all (and there are quotes stating that Webb mentioned 'slight' than the discussion should have been official and documented.
It was Aleix who made the discussion public, not Webb as without Aleix going public this would not be getting discussed as we would not have known.
But, I am sure that there is one thing we will agree on and that is were any other rider involved then no chat would have occurred.
On another side, I do wonder whether Rossi had the helmet on or off?
